SANITARY REBREATHING BAG Filed NOV. 18, 1940 INVENTOR Florence L. Shelton Patented Dec. 1, 1942 F'EENT OFFICE 1 Claim.

My invention relates to sanitary rebreathing bags that are to be used by physicians, nurses and others in the treatment of various maladies of the head, throat, and lungs.

A further object of my invention is to provide 7 simple and sanitary means for the giving of carbon dioxide treatments.

A still further object of my invention is to provide a simple device that may be used in the administering of various gases simultaneously or intermittently for the treatment of head, throat and lung maladies.

The invention is primarily intended for the use of physicians, surgeons, nurses, hospital attendants and others, and particularly for use by the medical, dental and nursing profession.

A further object of my invention is to provide a bag for use as an inhalent bag for the treatment of spasms of the larynx and respiratory organs. It is also useful for prophylactic treatments to prevent lung congestion, or atelectasis, or for the treatment of infarct.

Heretofore devices of this kind have been of permanent nature, expensive to make, and difiicult to maintain in a highly sanitary condition, and ones that because of the nature of their construction were used more than one time before being appropriately sterilized after the former use. This was necessitated because of the expense involved and the character of the construction and the time element involved.

Through the use of my improvement, the rebreathing bag is inexpensively made, is maintained in a sanitary condition until the time of the use, and after a single use is then discarded and a new one used.

While I do not wish to be limited in the manufacture of my bags to paper, yet I have found satisfactory results are to be obtained wherein inexpensive paper bags are used for this purpose to which I attach a tube or tubes and other attaching instrumentalities, making it possible to deliver the fluids for treatment directly into the bag from the source of supply, utilizing only a single rubber tube for effecting the transfer from the source of supply of the treating gas or gases directly to the bag.

This makes possible the utilizing of a breathing bag that is practically free from metal parts, one that is inexpensive to make, and one that facilitates the hospital having a relatively large stock on hand without the necessity of a large capital outlay being required.

With these and incidental objects in view, the

construction and combination of parts, the essential elements of which are set forth in the appended claim, and a preferred form of embodiment of which is hereinafter shown with reference to the drawing which accompanies and forms a part of this specification.

In the drawing:

Fig. I is a perspective side view of a paper bag in the bottom of which is removably attached a plurality of tubes which may be attached or detached therefrom when the bag is to be thrown away.

Fig. II is a perspective side view of a bag having a tube running transversely of the bottom of the bag and having ports disposed with central outlet tubes to permit the gases to be delivered into the bag escaping therefrom. In this view the bag is partially broken away to show the ports and the partition that is disposed within the tube central of the tube and between the ports disposed within the tube.

Fig. III is a side view of a bag of modified construction illustrating a tube communicating through the bottom of the bag, and a second tube communicating through the side of the bag.

Like reference characters refer to like parts throughout the several views.

I have found that satisfactory results are to be obtained Where paper bags of the conventional type may be used for a rebreathing bag for the treatment of head, throat and chest or lung maladies.

The treatment contemplates that one or more gases or other fluid medicaments may be administered simultaneously or one at a time, thus requiring a plurality of tubes being associated with the bag and through which the gases to be administered may be admitted into the interior of the bag. Best results being attainable where the bag I of the satchel type having a square bottom 2 is provided.

I attach a relatively heavy plate 3 preferably made of fibrous material and seal the same to the bottom 2 of the bag. The plate 3 is preferably covered until the time of use by a covering flap 4, in order to facilitate the removal of the flap from the outside of the plate I provide a han engaging tab 5.

Tubes here shown as three in number at 6, I and B are threaded at their engaging end as illustrated at 9 and a like number of holes are provided within the plate into which the respective tubes 6, 1 and 8 may be attached by threadinvention consists in certain novel features of ing the threaded end of the respective tubes into the plate, thus communicating the tube or tubes with the interior of the bag.

Rubber or other flexible hose connections may be secured to the end of the respective tubes to thereby permit the nurse or other attendant admitting gases for treatment into the bag.

The normal open end of the bag is placed over the face with the nose and mouth being disposed within the bag to thereby permit the patient inhaling the contents from the bag as the gases are admitted thereinto.

After the use of the bag, the tubes 6, l and 8 are then unthreaded from the plate and the breathing bag I is thrown away.

A modified form of bag may be made as illustrated in Fig. II wherein a single tube It runs transversely of the bag and at one side of the bag. The tube is partitioned as illustrated at l l and ports l2 and 13 are disposed within the tube and at either side of the partition to thereby per- A mit the admitting of at least two independent gases from the opposite ends l4 and [5 of the tubes into the bag simultaneously or one at a time.

In order that the bag may have substantial capacity and yet make the mouth of the bag sufficiently restricted to permit a fairly even engagement of the end I6 of the base with the face of the patient, I reinforce the bag at its top as illustrated at l! and i8 and make the open end of the bag of lesser width than the width of the bag thus giving a bag of greater gas capacity and yet limiting its open end as illustrated at It.

Where the bag is to be thrown away in its entirety, it may be made as illustrated at Fig. II and when so made the bag [9 and the tube l9 are fixedly secured together and after use the bag and the tube are discarded.

A slightly modified form of construction may be utilized as illustrated at Fig. III in which the bag 20 has a tube 2| extending through the bottom 22 of the bag, and the tube 2| is sealed to the bag on the inside and the outside as illustrated at 23 and 24 by any suitable plastic or fastening material. Thus providing a tube that communicates the interior of the bag with the outside.

"Where more than one gas is to be admitted into the bag, I provide a tube 25 disposed at one side of the bag and I secure the tube to the bag and place the inner end 26 of the tube on the inside of the bag, and pass the tube through the side wall 21 of the bag. The outer end 28 of the tube extends sufiiciently to facilitate the attachment of a tube 29 thereto that is used to admit the source of supply not here shown.

While I have described my bag as being made of paper, I do not Wish to be limited to the construction of the bag to paper, as it may be made of cloth, rubber or of other fibrous or nonfibrous material with equal facility. If paper is to be used, I recommend the use of a soft paper texture that does not create a noise when contacted with the face and one that will not be harsh, a fine tissue paper giving satisfactory results.

While I have here shown and described my invention as being comprised of a bag having tubes associated therewith, it will be apparent that gas might be admitted into the bag at any suitable location through the use of a needle of the hypodermic type. In order that'the bag may be reinforced at the point or points of puncture of the needle, a flange may be disposed upon the needle between its penetrating end and its base, or one or more pads may be secured to the bag to reinforce the same and the needle be made to penetrate the bag where reinforced. By the placing of the reinforcing on the outside of the bag its position and location would be apparent to the user of the same. I, therefore, do not wish to be limited to bags having tubes fixedly secured thereto as bags herein outlined may be used in conjunction with any hollow needle through which the gas would flow and emerge therefrom upon the interior of the bag.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claim which follows. i y I What I claim is:

In combination, a bag made of paper, said bag having a flat bottom and a restricted open end, a plate having a plurality of threaded holes secured to the bottom of the bag, a flap secured to the bag and arranged to cover the holes in the plate until the bag is to be used, and for removal as a cover for the holes when the bag is to be used, a tab formed integral with the flap, a plurality of threaded tubes, said tubes adapted for being threadably attached to the plate and for being passed through the plate and through the bottom of the bag to afford communication through the bottom of the bag and into the interior of the bag through the use of the tubes to permit rebreathing gas passing through the tubes and into the bag.
